    Verify your Google One cloud backup

    Open the Settings app and navigate to System > Backup. Ensure 'Backup by Google One' is toggled on and verify that 'App data,' 'Photos & videos,' and 'SMS text messages' have been synced recently. This serves as your primary safety net for critical data.

    Note: Manually tap 'Back up now' to ensure your most recent changes are captured.

    Clear the system cache partition

    Power off your device completely. Hold the Power and Volume Down buttons simultaneously until the Fastboot menu appears, then use the volume keys to navigate to 'Recovery Mode' and press Power to select. When the 'No command' screen appears, hold Power and press Volume Up once, then select 'Wipe cache partition' to remove temporary system files that may be causing instability.

    Note: This process does not touch your personal files or installed applications.
